The news got me to thinking of my own attempt, years ago, to peer inside an animal factory.

I was on a tour of a rural Iowa county, given by some farmers who
were angry that massive hog-raising facilities had been plunked down in
their community (I wrote about it here).
At one point, we got out of the van so I could gape at two rows of such
low-slung buildings, each holding thousands of hogs. A vast manure
cesspool separated the two rows.
